| Summary | VAAPI HEVC encoding is unstable and produces garbled output |
| Product | DRI |
| Version | DRI git |
| Hardware | x86-64 (AMD64) |
| OS | Linux (All) |
| Status | NEW |
| Severity | major |
| Priority | medium |
| Component | DRM/AMDgpu |

Do ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i 1080p_h.264_60fps.mp4 -c:v hevc_vaapi -qp 22 -tier high -c:a copy output.mp4 Several times and browse the web with Firefox while doing so. Sooner or lat= er (rather sooner) the encoding will either hang or the driver crashes complet= ely and I need to perform a hard reset. The encoding settings don't seem to matter as long -c:v hevc_vaapi is used. -c:v h264_vaapi seems to be totally stable. The encoding result of -c:v hevc_vaapi also shows a garbled line at the bot= tom of the video, while -c:v h264_vaapi looks fine. This is with a RX 580 mesa-git 19.1.0_devel.107212.ab940b0d972 linux 4.20.6 & drm-next-5.1-wip f9028b9278422fdf186f1b88662e28ed24e13df8 libva 2.4 ffmpeg-git b429c86d84cfc964c84bc68ec56799802de2b25a There seems to be a difference between linux 4.20.6 & drm-next-5.1-wip = though. I couldn't make the stable kernel crash entirely, instead just the encoding process started to hang.
I'm doing it the other way around hevc_vaapi 10 bit to h264_va=
api and have
similar results, garbled green output

Doesn't crash anymore, but there is still a garbled line at th= e bottom of video frames.
